For decades, the standard approach to legacy software has been the "Big Bang" rewrite—a high-risk, high-cost endeavor that attempts to rebuild aging systems from the ground up. This paper introduces the concept of the methodology. Rather than replacing legacy systems, "Weaving" focuses on gradually intertwining modern microservices and cloud-native components with the existing monolith. This approach minimizes operational risk, preserves institutional knowledge embedded in legacy code, and allows organizations to modernize at a sustainable pace.

| Weaving Term | Software Analogy | |--------------|------------------| | (vertical, continuous) | The legacy application – long-lived, stable, foundational | | Weft (horizontal, interlacing) | New services, APIs, cloud functions – built iteratively | | Loom | Integration middleware / enterprise service bus / API gateway | | Selvedge (finished edge) | Stable public interfaces (APIs) of the new system | | Tension | Operational governance – balancing change vs. stability | weave legacy app

A cloud-native, web-based application that can be accessed via a browser or a dedicated modern app, featuring automatic updates and AI tools.

Weaving fails when:

The “tangled weave” – ad hoc point-to-point connections without middleware. Leads to unmanageable complexity.

Weave strongly encourages users to move from the legacy version to the current desktop application to access modern features and improved performance.
